We assessed changes in transit-associated walking in the United States from 2001 to 2009 and documented their importance to public health.
We examined transit walk times using the National Household Travel Survey, a telephone survey administered by the US Department of Transportation to examine travel behavior in the United States.
People are more likely to transit walk if they are from lower income households, are non-White, and live in large urban areas with access to rail systems. Transit walkers in large urban areas with a rail system were 72% more likely to transit walk 30 minutes or more per day than were those without a rail system. From 2001 to 2009, the estimated number of transit walkers rose from 7.5 million to 9.6 million (a 28% increase); those whose transit-associated walking time was 30 minutes or more increased from approximately 2.6 million to 3.4 million (a 31% increase).
Transit walking contributes to meeting physical activity recommendations. Study results may contribute to transportation-related health impact assessment studies evaluating the impact of proposed transit systems on physical activity, potentially influencing transportation planning decisions.
我们评估了 2001 年至 2009 年美国过境相关步行量的变化，并记录了其对公共卫生的重要性。
我们使用国家家庭出行调查（National Household Travel Survey）来检查过境步行时间，该调查由美国交通部进行，旨在研究美国的出行行为。
如果来自低收入家庭、非白种人以及居住在有铁路系统的大城市，人们更有可能过境步行。在有铁路系统的大城市中，每天过境步行 30 分钟或以上的过境步行者比没有铁路系统的过境步行者更有可能多走 72%。从 2001 年到 2009 年，估计的过境步行者人数从 750 万增加到 960 万（增长了 28%）；那些过境相关步行时间为 30 分钟或以上的人数从大约 260 万增加到 340 万（增长了 31%）。
过境步行有助于满足身体活动建议。研究结果可能有助于评估拟议的过境系统对身体活动影响的与交通相关的健康影响评估研究，从而可能影响交通规划决策。
